The exposure parameters and dose quantities were collected manually. This retrospective, evaluative and comparative study was conducted to determine LDRLs for routine head CT examination in Bafoussam, to optimize these procedures in the region. The 75th percentile values of the calculated volume CT dose index (CTDIvol) and dose length product (DLP) were proposed as LDRL. The sample was classified in four age groups: &amp;lt;\u20091, 1\u20135, 5\u201310 and 10\u201315\u00a0y. The LDRLs obtained for the four age groups were: 24\u00a0mGy and 381.32\u00a0mGy.cm, 42.5\u00a0mGy and 875.55\u00a0mGy.cm, 45.85\u00a0mGy and 939.62\u00a0mGy.cm, 57.12\u00a0mGy and 1222.3\u00a0mGy.cm, respectively. The 75th percentile CTDIvol and DLP dose values for this study are higher than international values. We propose a coordinating discussions and collaboration about patient\u2019s and specific equipment\u2019s change information\u2019s, between radiologists, medical imaging technicians and medical physicist, which can reduce absorbed doses and improved medical practice in hospitals.<\/jats:p>","DOI":"10.1093\/rpd\/ncac143","type":"journal-article","created":{"date-parts":[[2022,6,20]],"date-time":"2022-06-20T02:50:11Z","timestamp":1655693411000},"page":"815-820","source":"Crossref","is-referenced-by-count":6,"title":["ESTABLISHMENT OF LOCAL DIAGNOSTIC REFERENCE LEVEL FOR ROUTINE PAEDIATRIC COMPUTED TOMOGRAPHY EXAMINATIONS IN BAFOUSSAM WEST CAMEROON"],"prefix":"10.1093","volume":"198","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5145-0023","authenticated-orcid":false,"given":"Eddy Fotso","family":"Kamdem","sequence":"first","affiliation":[{"name":"Mesoscopic and Multilayers Structures Laboratory, Department of Physics, Faculty of Science, University of Dschang , P.O.
